. DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 268,700, dated December 5, 1882.

- Application filed July 5, 1882. (No model.) I

To all whom it may concern:

Be it known that 1, JAMES Lrrcn, of Laurinburg, in the county of Richmond and State of NorthGarolina, have invented certain new and useful Improvements in Door-Checks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to an improvement in checks for doors, gates, shutters, and other similar devices; and it consists .in certain de tails in construction and combination of parts, as will be more fully described, and pointed out in the claim.

In the accompanying drawings, Figure l is a perspective ,view of my improvement secured to a door-frame, and Fig. 2 is a detached view of the check.

A represents a door-frame, and B the door,

hinged thereto in the ordinary manner.

My improved check 0 consists of the stationary semicircular bar Ct and the verticallymovable semicircular bar a,the latter being .secured to the said stationary bar a by the setscrews D. The opposite ends of the stationary bar a are bent or curved at right angles to the main body portion thereof, and provided with openings, by means of which it is secured in position by screws to the doorframe above the door, or to a window-casing above or below the shutters. This bar is either U-shaped or semicircular in form, and is pro vided at suitable intervals apart with femalescrew-threaded openings, in which the setscrews D rest and move. I prefer to use three screws, placed as shown in the accompanying drawings; but any suitable number can he used that'will answer the necessary purpose. The lower ends of these screws D are swiveled to the movable semicircular bar a, and

.it follows that as the screws 1) are turned either to the right or left the bar a is caused lower bar, a, is similarin shape to the barn, and is provided with the beveled ends 0, which enablesthe upper edge of the door to move under and engage the plate without meeting any sharp edges, which would injure the same.

The improved check is placed over the door or gate, on the hinge side thereof, and is so situated as to engage the door as soon as it begins to turn on its hinges, and bear thereon throughout its entire movement. The screws D can be turned in the same direction, so as to force the entire bar down, or only one screw D can be turned, so as to cause the bar a" to bear on the door when the latter passes under the depressed portion thereof.- When the bar a, is forced downward it bears on the top of the door, and by frictional contact therewith holds the. same in any desired position and prevents the same from slamming. The door is free at all times to be moved when snfficient force is used, and the size and construction of the screws D are such as to prevent the plate a from being moved downward sufficiently to completely lock the door.

Instead of using screws D, as above described, springs can be inserted between the metallic bars (6 a, and answer all the necessary purposes.

My improvement can be used on gates and window-shutters, and operate in a like manner to that above described. nection with window-shutters the bars a a When used in con-' could be secured under the shutters, instead of over them, and answer all the necessary purwith beveled end, and set-screws D, swiveled in the bar a and fitted in screw-threaded open ings in plate a, substantially as set forth.

In testimony whereofI have signed this specification in the presence of two subscribing wituesses.
